Fix a regression that broke rendering of unicode regional indicators

Browse Source 
At some point, unicode regional indicators became combining chars in the
unicode standard, which broke the handling of them in draw_codepoint().
The fix has the added advantage of improving performance in the common
case by only checking for combining chars. The flag check happens only
if the first check matches.

Fixes #4407
